The formula
Roof area = house footprint x pitch multiplier x 1.10 overhang factor; Cost = roof area x material rate + tear-off + permit
Roofers price in squares. One square is 100 square feet of roof area — not floor area. A steeper roof covers more surface for the same footprint, which is why pitch matters so much.
Worked example
A 2,000 sq ft single-story home with a 6:12 pitch has roughly 2,464 sq ft of roof, or about 24.6 squares. At $9 per square foot for architectural shingles, that is about $22,000 before tear-off credits and permit fees.
Frequently asked questions
How many squares is a 2,000 sq ft roof?
A 2,000 square foot roof surface is 20 squares. If 2,000 square feet is your house footprint, the roof surface is larger — usually 22 to 28 squares once pitch and overhangs are included.
How much does a new roof cost in Florida?
Most Florida asphalt shingle replacements land between $9,500 and $25,000 in 2026, with metal and tile roofs running considerably higher. Wind-uplift requirements and secondary water barrier rules add cost versus other states.
Is tear-off included in roofing quotes?
Usually yes, but confirm it. Tear-off and disposal typically add $1.00 to $1.75 per square foot per layer removed.
